SQLite is the Plugin that stores the data in the device in the form of Tables.

It helps to maintain the data in rows and columns in the Mobile local directory. we can run SQL queries to perform CRUD operations (Create, Read, Update, delete)

So to start Using the Sqlite in flutter add the plugin in the dependencies:

dependencies:
  flutter:
    sdk: flutter

#dependencie of SQLITE
  sqflite: ^2.2.0+3
  path_provider: ^2.0.11

Then make a separate file for using all the database queries and creating a database.

Import the statements and create the database helper class:

import 'package:sqflite/sqflite.dart';
import 'package:path/path.dart';


class DatabaseHelper{

}

In this class create the future method for creating a database and which will return the database when needed.

There is an openDatabase() function that comes in the SQLite package, which takes three parameters. first takes the path of the database where the database file will be stored and the second one takes the onCreate call back function which calls when the database is not there in the provided path and needs to be created. third is the version that takes the integer value.

Here is the function for that:

  final String _tableName = "users";

  Future<Database> getDataBase() async {
    return openDatabase(
      join(await getDatabasesPath(), "usersDatabase.db"),
      onCreate: (db, version) async {
        await db.execute(
          "CREATE TABLE $_tableName (id TEXT PRIMARY KEY, name TEXT, imageUrl TEXT)",
        );
      },
      version: 1,
    );
  }

Also created one variable that stores the table name.

So here is how to create the Database function which creates the local database table.
